My current mini mouse broke so had to order a replacement. While this is certinaly slim, I am disappointed in the way it works and seems to have a conflict with other devices occasionally.

i first got this mouse 2 years ago.It's comfortable to the hand and when i say its ultra low power,its low power..batteries last for a loong time

...when we tried one (from the 4 ordered). We didn't intend to order the small model, but they are so awesome. Don't feel too small. Slick, light, responsive.
